Installation Technology of Installable Precast Concrete Stairs

近年来,装配式建筑在国内房屋建设中应用越来越广,预制楼梯作为装配整体式结构体系中一个重要组成部分,在实际施工中常出现梯板安装偏位、搁置长度不足以及踏步碰损等不合格情况,对分项工程的验收和整个项目的工期造成了影响。文章结合南京市栖霞区丁家庄二期保障房工程,介绍了装配式预制楼梯的安装工艺流程,针对施工过程中出现的主要问题进行着重分析,并提出相应的质量控制措施。

In recent years, assembly type building in domestic housing construction in the application increasingly wide, prefabricated stairs as assembly overall type structure system in the a important part, in actual construction in the often appeared ladder Board installation partial bit, and shelved length insufficient and stepping touch loss, not qualified situation, on points items engineering of acceptance and whole project of duration caused has effect.Ding Jia village, qixia district, Nanjing city, combined with second-stage housing project, precast stair installation process is introduced, analyses the major problems arising in the course of construction, and puts forward relative quality control measures, can provide technical reference for similar projects.
